I added the following to the lines stylefile

after the line

highway=motorway {add oneway = yes; add bicycle = no; add foot = no } [0x01 road_class=4 road_speed=6 resolution 12]

#handling specific long distance connector routes

highway=trunk & (ref=N1|ref=N2|ref=N3|ref=N4) [0x02 road_class=4 road_speed=5 resolution 12]

I would guess you would get even better routing using
highway=motorway {add oneway = yes; add bicycle = no; add foot = no } [0x01 road_class=4 road_speed=7 resolution 12]
highway=trunk & (ref=N1|ref=N2|ref=N3|ref=N4) [0x02 road_class=4 road_speed=6 resolution 12]
highway=trunk [0x02 road_class=4 road_speed=5 resolution 12]

I'ld actually go so far to put all road_class=4 and road_speed=7 - though then you're estimated arrival times will get a bit quick..

cGpsMapper manual should not be trusted regarding their proposals - best is trial and error but changing few variables at a time.

Thanks. I'll try this out. The cGPSMapper manual contains the following fairly obscure statement:

...it is important to prepare data with non broken road network keeping specific road class...

This might be related to the reason for your longer routing distances.

Cheers.
